Description

The MC34262/ MC33262 are active power factor controllers specifically designed for use as a preconverter in electronic ballast and in off line power converter Oct 29, 2003 gives recommendation for design changes of existing systems using competitor part of the TDA 4863 such as L6561, MC33262 and others. ON Semiconductor has developed three controllers ( MC33262 , MC33368 and. MC33260) that operate in critical mode and the NCP1650 for continuous mode MC33262 critical conduction mode control chip and a single. IGBT. The internal circuit architecture of the chip is shown in Figure 4. Referring to these figures the MC34262 MC33262 . MAXIMUM RATINGS. Rating Symbol Value Unit.
